Display apparatus with transmissive and reflective subpixels

Abstract

A display apparatus includes a display section including an array of pixels in a two-dimensional matrix, wherein each of the pixels of the display section includes a pair of a subpixel displaying a first primary color, and a subpixel displaying a second primary color being different from the first primary color.

What is claimed is: 
     
       1. A display apparatus comprising:
 a transreflective display section including a liquid crystal panel comprising
 an array of pixels in a two-dimensional matrix, 
 a plurality of scan lines, 
 a plurality of signal data lines, 
 a scanning circuit for supplying scanning signals and being connected to the plurality of scan lines, and 
 a signal output circuit for supplying video signals for displaying a red color, a green color, and a blue color and being connected to the plurality of signal lines; wherein, 
 each of the pixels of the liquid crystal panel includes:
 (i) subpixels including (a) a first transmissive subpixel comprising a red filter, (b) a second subpixel comprising a green filter, (c) a third subpixel comprising a blue filter, (d) a first reflective subpixel comprising a red filter, and (e) a fourth subpixel comprising a white filter or a cyan filter, where (1) the second subpixel and the third subpixel are both transmissive subpixels and the fourth subpixel is a reflective subpixel or (2) the second subpixel and the third subpixel are both reflective subpixels and the fourth subpixel is a transmissive subpixel; 
 (ii) a first transistor that connects a first signal line for supplying a video signal for displaying red color to pixel electrodes of the first transmissive subpixel and the first reflective subpixel in response to an application of a respective scanning signal from a scanning line to a gate electrode of the first transistor; 
 (iii) a second transistor that connects a second signal line for supplying a video signal for displaying green color to pixel electrodes of the second subpixel and the fourth subpixel in response to the application of the respective scanning signal from the scanning line to a gate electrode of the second transistor; and 
 (iv) a third transistor that connects a third signal line for supplying a video signal for displaying blue color to a pixel electrode of only the third subpixel in response to the application of respective scanning signal from the scanning line to the gate electrode of the third transistor. 
 
 
 
     
     
       2. The display apparatus of  claim 1 , wherein the second subpixel and the third subpixel are both transmissive subpixels and the fourth subpixel is a reflective subpixel. 
     
     
       3. The display apparatus of  claim 1 , wherein the second subpixel and the third subpixel are both reflective subpixels and the fourth subpixel is a transmissive subpixel. 
     
     
       4. The display apparatus of  claim 1 , wherein an area of the first transmissive subpixel is different than an area of the fourth subpixel. 
     
     
       5. The display apparatus of  claim 4 , wherein the area of the first transmissive subpixel is smaller than the area of the fourth subpixel. 
     
     
       6. The display apparatus of  claim 1 , wherein an area of the first reflective subpixel is different than an area of the fourth subpixel. 
     
     
       7. The display apparatus of  claim 6 , wherein the area of the first reflective subpixel is smaller than the area of the fourth subpixel.
